Running a Java process in Windows even after the user is logged out

Question

I have a batch file that starts a Java process in a Windows 2003 server. As per the security policy, the users of that machine are logged off forcefully, if the user is inac

Answer 1

I'm using Java Service Wrapper to start the java process as windows service. I guess it works similary to the srvany.exe mentioned in the previous posting.

Answer 2

As per my analysis,

The Idle Solution will be writing a VC++ (.net) Windows Service creation program to launch the .bat / .exe as a System service with all the required call back methods to SCM.

Note : 1. Wrapping the process with srvany.exe would not work as it does not have any call back process to the SCM (Service Control Manager). 2. And java service Wrapper is a third party API (many are LGPL licensed).

Answer 3

If you want it to run under Scheduled tasks you have to make sure you don't have "only run when user logged in" checked, which usually means you need to supply a password.

A windows service would be the normal way to do this: the Java service wrapper is 3rd party but loads of people use it.

If you really wanted to not use a 3rd party method you could use svrany.exe (http://support.microsoft.com/kb/137890) on WIndows NT or later, but it is not designed specifically for Java.

Answer 4

Wrapping the process with srvany.exe and launching as a service would work as well.

I don't know it this is relevant but we are using a flag to the jvm so it does not shutdown on logoffs

"java -Xrs"
